Integrable models, degenerate horizons and AdS_2 black holes
J. Cruz, A. Fabbri, D. J. Navarro +2
The near extremal Reissner-Nordstrom black holes in arbitrary dimensions ca be modeled by the Jackiw-Teitelboim (JT) theory. The asymptotic Virasoro symmetry of the corresponding J…
On the normalization of Killing vectors and energy conservation in two-dimensional gravity
J. Cruz, A. Fabbri, J. Navarro-Salas
We explicitly show that, in the context of a recently proposed 2D dilaton gravity theory, energy conservation requires the ``natural'' Killing vector to have, asymptotically, an un…
Free Fields for Chiral 2D Dilaton Gravity
J. Cruz, J. Navarro-Salas, M. Navarro
We give an explicit canonical transformation which transforms a generic chiral 2D dilaton gravity model into a free field theory.
Free Field Realization of Cylindrically Symmetric Einstein Gravity
J. Cruz, A. Mikovic, J. Navarro-Salas
Cylindrically reduced Einstein gravity can be regarded as an sigma model coupled to 2D dilaton gravity. By using the corresponding 2D diffeomorphism algebra of cons…
Symmetries and solvable models for evaporating 2D black holes
J. Cruz, J. Navarro-Salas, M. Navarro +1
We study the evaporation process of a 2D black hole in thermal equilibrium when the ingoing radiation is switched off suddenly. We also introduce global symmetries of generic 2D di…
New Symmetries in Two-Dimensional Dilaton Gravity
J. Cruz, J. Navarro-Salas, M. Navarro +1
We present three types of non-conformal symmetries for a wide class of 2D dilaton-gravity models. For the particular CGHS, or string-inspired model, a linear combination of these s…
